Google has unveiled its latest "doodle" on its homepage, celebrating the 20th
anniversary of Wallace and Gromit.

When users click on the Google logo, they are directed to a results page featuring the Aardman Animations characters created by Nick Park.

The characters Wallace and Gromit have become two of the most recognisable faces of modern British culture. They first appeared in A Grand Day Out 20 years ago, a 30-minute film where the pair travel to the moon to obtain cheese, Wallace's favourite food.

The pair have starred in a number of 30-minute films since, including The Wrong Trousers, A Close Shave and A Matter of Loaf and Death, and one feature-length film, The Curse of the Were-Rabbit, which won an Oscar for Best Animated Feature Film.

Google released a special misspelt version of its own name – as "Googlle" – to mark the company's 11th birthday and it recently sparked internet speculation with a series of UFO-themed doodles to mark the anniversary of the birth of the War of the Worlds author, HG Wells.
